[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0022] The embodiment of the present invention provides a method for displaying document content, such as Figure 1 As shown, including:

[0023] S101. Obtain the instruction input by the user to perform a screen flipping operation on the document; specifically, the screen flipping can be to flip the document forward so that the user can read the content of the previous screen of the document; or it can be to flip the document backward so that the user can read the content of the next screen of the document. The document may include a word document, a pdf document, a ppt document, etc. When the document is opened, the content displayed on the current interface of the document can be analyzed in real time to extract the core content of the current interface. The core content includes (a) the table header and the table subject, or the subject of the image, that is, public information; (b) summary information of the core content of the table or image, that is, feature information. When the user has finished reading the content displayed on the current interface of the document, the screen flipping operation can be performed, and the instruction input by the user to perform the screen flipping operation on the document can be obtained.

[0024] S102. Perform a screen flipping operation on the document according to the instruction, identify the first table or the first image displayed on the current interface of the document after the screen flipping operation, and extract the first characteristic information of the first table or the first image; specifically, the document can be flipped according to the instruction, and after the screen flipping operation, the content displayed on the current interface of the document can continue to be analyzed. When the content displayed on the current interface of the document includes the first table or the first image, identify the first table or the first image displayed on the current interface of the document, and then extract the first characteristic information of the first table or the first image. The first characteristic information is the summary information of the core content of the first table or the first image.

[0025] S103. Obtain first public information corresponding to the first characteristic information, where the first public information is extracted from the second table or the second image of the document before the screen flipping operation; specifically, the first public information includes a table header and a table subject, or an image subject. After extracting the first characteristic information of the first table or the first image, the first public information corresponding to the first characteristic information can be searched from the core content extracted before the screen flipping operation.

[0026] S104. Display the first public information on the current interface. Specifically, after finding the first public information corresponding to the first characteristic information, the first public information can be displayed on the current interface. The first public information can be displayed on the current interface in the form of a floating window. The first public information can be displayed above the screen or below the screen. Thus, in the case where the first table or the first image has the same or matching first characteristic information as the second table or the second image, the first public information of the second table or the second image of the previous screen or the previous screens can be displayed on the current screen, so that the public information of one or a table or an image that is divided into two parts and set on two pages can be visible on both pages.

[0027] The method for displaying document content provided by an embodiment of the present invention obtains an instruction input by a user to turn the screen of a document; turns the screen of the document according to the instruction, identifies a first table or a first image displayed on the current interface of the document after the turning the screen operation, and extracts first characteristic information of the first table or the first image; obtains first public information corresponding to the first characteristic information, the first public information being extracted from a second table or a second image of the document before the turning the screen operation; and displays the first public information on the current interface; thereby, when a table or an image is divided into two parts and set on two pages, when the user turns to the content behind the table or image, the public information of the table or image will be displayed on the current interface, so that the public information of the table or image is always visible, which can improve the user experience.

[0028] In an optional embodiment, in step S101, before obtaining the user input instruction to turn the document, the method for displaying the document content also includes: identifying a second table or a second image displayed on the current interface in the document; and extracting second feature information and first public information of the second table or the second image.

[0029] Specifically, the content displayed on the current interface of the document can be analyzed in real time. Before the screen flipping operation, when the content displayed on the current interface of the document includes a second table or a second image, the second table or the second image displayed on the current interface of the document can be identified, and then the second characteristic information and the first common information of the second table or the second image can be extracted. The second characteristic information is the summary information of the core content of the second table or the second image.

[0030] In an embodiment of the present invention, before the screen turning operation, by identifying the second table or the second image displayed on the current interface in the document and extracting the second characteristic information and the first public information of the second table or the second image, the second characteristic information and the first public information of the second table or the second image displayed on the current screen when the screen is turned can be obtained. Therefore, when the first table or the first image associated with the second table or the second image is displayed on the next screen, the first public information can be displayed on the next screen, which can be convenient for user reading and improve user experience.

[0031] In an optional embodiment, step S103, obtaining first public information corresponding to the first characteristic information, includes: finding second characteristic information that satisfies a similar condition to the first characteristic information; and finding first public information corresponding to the second characteristic information.

[0032] Specifically, since the first characteristic information is the summary information of the core content of the first table or the first image, and the second characteristic information is the summary information of the core content of the second table or the second image, if the first table and the second table are the same table, or the first image and the second image are the same image, the first characteristic information should match the second characteristic information, and if the first characteristic information is similar or identical to the second characteristic information, the second characteristic information can be found through the first characteristic information, and then the first common information corresponding to the second characteristic information can be found.

[0033] In an embodiment of the present invention, by finding the second characteristic information that meets similar conditions as the first characteristic information, the first public information corresponding to the first characteristic information can be quickly found, and then the first public information can be displayed on the current interface, so that the public information of the same table or the same image is always visible, thereby improving the user experience.

[0034] In an optional embodiment, in step S102, after extracting the first characteristic information of the first table or the first image, the method for displaying the document content further includes: extracting the second public information of the first table or the first image; and when it is determined that the second public information does not exist, obtaining the first public information corresponding to the first characteristic information.

[0035] Specifically, after the screen flipping operation, when the content displayed on the current interface in the document includes the first table or the first image, in addition to extracting the first characteristic information of the first table or the first image, the second public information of the first table or the first image can also be extracted to determine whether the second public information of the first table or the first image exists. The second public information includes a table header and a table subject, or an image subject. If the second public information exists, it means that the first table or the first image displayed on the current interface has a table header and a table subject, or an image subject, and the first public information of the second table or the second image does not need to be displayed on the current interface. If the second public information does not exist, it means that the first table or the first image displayed on the current interface does not have a table header and a table subject, or an image subject, then the first public information corresponding to the first characteristic information can be obtained, and the first public information can be displayed on the current interface.

[0036] In an embodiment of the present invention, the second public information of the first table or the first image is extracted, and the first public information corresponding to the first characteristic information is obtained only when it is determined that the second public information does not exist. Therefore, when the second public information of the first table or the first image exists, the first public information of the second table or the second image is not displayed on the current interface, thereby reducing unnecessary display of the first public information.

[0037] In an optional embodiment, extracting the first public information of the second table or the second image, or extracting the second public information of the first table or the first image, includes: performing text recognition on the first table or the first image, or the second table or the second image, to obtain a recognition result; when confirming that the first table or the first image, or the second table or the second image includes annotation information based on the recognition result, extracting the annotation information to obtain a table subject or an image subject; when confirming that the first row of the first table or the second table includes a specific font or specific characters based on the recognition result, extracting the first row of the first table or the second table to obtain a table header.

[0038] Specifically, the specific font includes a bold font, and the specific characters include a serial number, a number, a serial number, etc. When extracting the first public information or the second public information, the first table or the first image, or the second table or the second image can be subjected to text recognition. Since the subject of the table belongs to the annotation information and generally appears above the table, and the subject of the image also belongs to the annotation information and appears above or below the image, when the annotation information is recognized, the annotation information can be extracted to obtain the table subject or the image subject. For the header, it is generally set in the first row of the table and displayed in bold. The text in the table can be processed as follows: 1. When a bold font is detected, the bold font is given a score, and then the weight is compared. The row or column with the largest weight is the table header; 2. Some default keywords are set, such as serial numbers, numbers, serial numbers, etc. If it is detected that the first row of the table includes these keywords, the first row of the table is the table header; through the above processing, the table header can be extracted.

[0039] Since the technology of text recognition is quite mature, in the embodiment of the present invention, by performing text recognition on the first table or the first image, or the second table or the second image, the first public information or the second public information can be accurately extracted according to the text recognition result.

[0040] In an optional embodiment, extracting the first feature information of the first table or the first image, or extracting the second feature information of the second table or the second image, includes: performing text recognition on the first table or the first image, or the second table or the second image, to obtain a recognition result; performing semantic analysis on the first table or the first image, or the second table or the second image according to the recognition result to obtain corresponding first feature information or second feature information.

[0041] Specifically, when extracting the first characteristic information or the second characteristic information, text recognition can be performed on the first table or the first image, or the second table or the second image. Then, context analysis is performed based on the text recognition result to determine the attribute information in the table, and semantic analysis is performed on the attribute information in the table to analyze the meaning of the attribute information and obtain the corresponding first characteristic information or the second characteristic information.

[0042] Since the technology of text recognition is quite mature, in the embodiment of the present invention, by performing text recognition on the first table or the first image, or the second table or the second image, the first feature information or the second feature information can be accurately extracted according to the text recognition result.

[0043] In an optional embodiment, in step S104, after displaying the first public information on the current interface, the method for displaying document content further includes: acquiring a user's move operation on the first public information; and moving the first public information according to the move operation.

[0044] Generally, the first public information is displayed at the top or bottom of the screen. However, if the user wants to drag the first public information to another location, if the first public information can be dragged, the user experience can be improved. Therefore, the embodiment of the present invention obtains the user's move operation on the first public information, and moves the first public information according to the move operation, so that the first public information can be moved according to the user's needs, which can improve the user experience.

[0045] In order to better understand the present invention, the present invention is further described below using a table as an example.

[0046] When a user opens a document through an electronic device, the data analyzer can be triggered to perform real-time analysis on the content of the document. The data analyzer can perform text recognition on the document displayed on the current interface. When it is recognized that there is a third table on the current interface, such as Figure 2 As shown, the third public information and the third characteristic information in the third table can be extracted, and the third public information includes the third table subject and the table header, such as Figure 2 The third characteristic information is the summary information of the core content of the third table.

[0047] When extracting the third public information of the third table, the annotation information of the third table may be extracted first, for example, Figure 2 The annotation information above the third table in the third table is obtained to obtain the subject of the third table. Then the bold words in the third table are identified, and the bold words are scored. Then the scores of all rows and columns in the third table are compared, and the row or column with the largest score is the header of the third table, such as Figure 2 As shown, the first row of the third table is all bold words, the first row of the third table has the largest score, and the first row of the third table is the header of the third table; further, in order to improve the accuracy of the extracted header of the third table, some serial numbers, digits, and numbers can be set to identify whether the first row of the third table includes these serial numbers, digits, time or numbers. If the first row of the third table includes these serial numbers, digits, time or numbers, for example, the first row of the third table includes serial numbers one, two, three, and four, and also includes time, and the score is the largest, then the first row of the third table is the header of the third table, and then the content of the first row of the third table is extracted to obtain the header of the third table.

[0048] When extracting the third characteristic information of the third table, semantic analysis can be performed on the content of the third table, the context in the third table can be analyzed, and the core content of the third table can be summarized. For example, Figure 2The third table shown can be analyzed through semantic analysis to find that the first column of the third table lists multiple attributes, and the contents of the second to fifth columns are used to describe the multiple attributes respectively. Then the contents obtained by the analysis are recorded to obtain the third feature information.

[0049] Then, after the user scrolls back, the data analyzer continues to analyze the content of the document and performs text recognition on the document displayed on the current interface. When it is recognized that the current interface has a fourth table, Figure 3 As shown, the fourth public information and the fourth characteristic information in the fourth table can be extracted, the fourth public information includes the fourth table subject and the table header, and the fourth characteristic information is the summary information of the core content of the fourth table.

[0050] like Figure 3 As shown, since there is no annotation information in the fourth table, the subject of the fourth table cannot be extracted. Also, since there is no bold font in the fourth table and the first line does not include specific characters such as serial number, number, time or number, the table header cannot be extracted. Thus, the fourth public information cannot be extracted.

[0051] When extracting the fourth feature of the fourth table, semantic analysis can be performed on the content of the fourth table, the context in the fourth table can be analyzed, and the core content of the fourth table can be summarized. For example, Figure 3 The fourth table shown, through semantic analysis, can be analyzed that the first column of the fourth table lists multiple attributes, and the second to fifth columns are used to describe the multiple attributes respectively. Then the content obtained by the analysis is recorded to obtain the fourth feature information.

[0052] By comparing the third characteristic information with the fourth characteristic information, it can be found that the first column of the third table and the first column of the fourth table both list multiple attributes, and the second to fifth columns are used to describe the multiple attributes, so the third characteristic information is similar to the fourth characteristic information. And because the fourth public information is not extracted, the third public information corresponding to the third characteristic information can be displayed in the form of a floating box on the current interface, so that the user can better read and understand the content of the fourth table based on the third public information, thereby improving the user experience.

[0053] The embodiment of the present invention provides a device for displaying document content, such as Figure 4 As shown, including:

[0056] The acquisition unit 23 is used to acquire the first public information corresponding to the first characteristic information, where the first public information is extracted from the second table or the second image of the document before the screen flipping operation.
